DH has had a subcutaneous cyst on his neck for years. About 5 years ago it got huge and infected and popped. It then went down to almost nothing.
Over the years it re grew. It has been about 1cm in size and not changed for about 3 years.
2 days ago it suddenly grew twice the size and today it has a secondary mound which is white. He says it is quite sore.
As this secondary white head has come up, is there something we can put on it like magnesium sulphate or similar?
Any advice? He will get in touch with his GP tomorrow.
The GP was reluctant to operate on it previously due to its position.
